CENTRIF'UGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,985, dated May 1, 1883.

" Application filed OetoberIG IBBQ. (No model.)

Be it known that. I, OLEMENsvoN TOLSHEIM, a subject of the Em'peronof Germany, and a resident of Munich, Germany, have invented new and useful Improvements in Centrifugal Machines, which the following isa specification: i

My invention relates'to that class of contrifugal machines which are continuous in their action, or in which. the introduction of the substance to be dried and the delivery of the dried substance and the liquid separated therefrom resents a vertical section of a machine embody are both performed continuously.

The invention consists in novel combinations of parts hereiuafterklescribed, and pointed ou't in the claims. V i i In the accompanyingdrawings, Figure 1 reping myinvntion, in which the axis of rotation of the sphere or drum is horizontal. Fig. 2 represents one of the journals of the rotary sphere or drum and appurtenances slightly modified in form. Figs. 3 and 4'represent sectional views, in planes at rightangles to each other, of a feeding apparatus which I employ, but which I do not claim as a part of this invention. Fig. 5 represents a vertical section of a machine inwhich the sphere or drum ro-.

tates on a vertical axis, and which also embodies my invention and Fig.6 represents a sectional view of a drying apparatus, through which thesubstance may be passed, if desired, after being delivered from the centrifugal machine, but which I do not claim as a part of this invention.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1, 2, 3, and 4, A designates a hollowsphereor drum, rotating with great rapidity upon ahorizontal axis, and ac designate the journals or trunnion s thereof,

the bearings not being here shown.

B designates a cylindrical sieve, which is pivoted in the sphere or drum by a boltor rod, B, which bolt or rod intersects the axis of the sphere or. drum obliquely. The sieve B rotates very slowly. in a plane which intersects the axis of rotation of the sphere or drum A.

The said cylindrical sieve B is divided internally by the. blades b into cells, into which the damp salt or othersubstance is fed through a tube, 0, that passes through the hollow jourwill be forced away through the sieve. two half-spheres which constitute. the sphere somewhat distant without further, means transport, fan-blades f are placed round 13W fnal or trunnion a, and the salt enters through of the belt or rod B, the salt reaches a greater radius of rotation with respect to the axis of the sphere or drum A, and therefore the water or drum are secured thereto so that there is a space, 0, between them, and water thus finds an outlet from the centrifugal apparatus into the rim d,-whence it is led away by means ofa 6 tube. The rim is stationary, and constitutes a receiver surrounding the sphere A. As the rotation continues round the axis of the sphere or drum the salt reaches theother side of the said axis, and there, in consequence of the cen- 7o trifugal force, leaves the cells. A partition, e,

divides the sphere or drum A into two chambers, e 0 into the latter of which the salt is thrown from the cells of the sieve. The dried salt leaves the chamber 0 through holes f, and 7 5 is delivered into the surrounding stationary receiver f, from which it is carried away by a tube whose outlet is tangential to it. a

'In order to cause the salt to reach a place sphere or drum A to form a blower, and send 1 forth, togetherwith the salt, a powerfulcurrent 'ofair, and thus carry the salt to a distance. The journal at carries'a pulley, g, by means of which 8 The said the centrifugal apparatus is driven. k journal is made hollow, and there is in it a pin, it, whose rotation is prevented by an arm,

s, and which is pressed against the disk B of the sieveB by means of a spring, h. The

diskrolls upon the said fixed pin, it by friction, and thus receives a slow rotary motion upon the axis of its rod B.

The hollowjournal, the pulley, the circular sieve, and the plate-shell which carriesitform a rigid system whose center of gravity must be at the point of intersection ofthe two axes,

and which is fixed by a screw that goes through that point.

. Instead of having a spring h pressing against the end of the pin h, as in'I ig. 1, the pin may be pressed inward by a spiral spring, h as shown in Fig. 2.

The introduction of the wet salt through the The 60 A fixed tube may be produced by means of a feeding-screw or conveyer,O, similar to that employed in a peat-press, and as shown in Figs. 3 and 4; or it may be brought through cylinders or by other suitable means.

The centrifugalapparatus, as above described, is in the horizontal position. It may, however, be arranged in the vertical position, as shown in Fig. 5, and in this case also consists essentially of a sphere or drum A and a sieve B'rotating upon axes intersecting each other obliquely, and is constructed generally in a similar manner to that already described. The differences which exist between the two constructions are briefly enu- Inerated as follows: In the horizontal construction the pin h, through which the rotasame and into the continuous drier represent tion of the sieve B is brought about, is pressed against the disk B by means of a spring, while in the vertical construction the whole weightof the centrifugal apparatus rests upon the pin, whose height may be regulated by a screw, 2. The space cutoff by the partition 6, in which the salt congregates, is in the horizontal construction placed at the left side, while in the vertical construction it is at the lower part of the apparatus. The feeding in of the salt takes place in the horizontal construction by means of the arrangement represented in Figs. 3 and 4, while in the vertical construction it falls in over a shaking apparatus freely through the funnel and tube 0.

The bearings in which the journals a a. of the sphere or drum rotate are supported by blocks j, of iudia-rubber or other material. These blocks form elastic cushions, which obviate the shaking resulting in acentrifugal apparatus from the center of gravity not being exactly in the axis of the journals on which the sphere or drum rotates. The shell or drum A in Fig. 5 is rotated by a belt, D, from a driving-shaft, D.

Should the salt be very fine, and in consequ'nce not be suflicienly dried by the centrifugal apparatus, it is made to pass out of the ed in Fig. 6. It consists of a shallow channel, E, heated by direct firing, or by steam, and

scrapers E, fastened to an endless band, E

and serving to draw the salt over the channel substance and liquid are continuously delivered, are not new, and hence I do not seek to cover, broadly, such a machine.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the rotary drum or sphere A, of the sieve B, arranged and adapted to rotate therein in a plane intersecting the axisof said drum or sphere, so that material of said sieve by centrifugal force as soon as it is carried by the rotation of said sieve across the plane of the axis of said drum or sphere, and a feed-tube,'0, for delivering the substance to be dried into said sieve, all constructed and capable of operation substantially as herein de- 7 5 scribed.

2. The combination, with the rotary drum or sphere A, divided'by apartition, 0, transverse to its axis, and provided with deliveryopenings b f on opposite sides of said partition,

of the sieve B, arranged and adapted to rotate within said drum or sphere in a plane intersecting the axis of said drum or sphere, so that the substance introduced into said sieve will be retained therein by centrifugal force so long as it remains on one side of the plane of the axis of said drum or sphere and on one side of the partition 6, and will be thrown out of said sieve by centrifugal force as soon as it is carried by the rotation of the sieve across the 0 plane of the axis of the drum or sphere and on the other side of the partition 6, and the feedtube 0, for delivering the substance to bedried into said sieve, all constructed and capable of operation substantially as herein described. 9 5

3. The combination of the sphere or drum A, divided by the partition 6, and provided with delivery-openings b f on opposite sides of said partition, and with the fan-blades f adjacent to the openings f of the circular stationary receivers'cf, and the sieve B, having its axis oblique to that of the sphere or drum, and adapted to rotate in a plane intersecting said axis, substantially as and for the purpose herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
